sub floor replacement

I have removed a subfloor in the bedroom of my home over a crawl space. What is recommend for attaching the new subfloor, i.e. glue, nails, screws? The thickness of the replacement floor is 2 inches.

I am not sure what you are looking for, but for sub floors I always use at least 3/4" T&G subfloor plywood. Sometimes I use 1", but I never use OSB for sub flooring. I put glue on the top of all studs. I use the PL brand. I then screw the sub flooring down using 2" torgue head stainless steel screws, 6" apart. I stagger the sheets so I do not have continuous sub flooring edges. Hope this helps.

Likewise, I use 3/4" Advantech, or the equivalent. They have a wax like impregnation that prevents water from soaking in during construction.
